Abstract

The relative amount of ethanol and xylitol accumulated in aerobic batch cultures of Pachysolen tannophilus and Candida guilliermondii on d-xylose depended on the extent of limitation by biotin. In high biotin media P. tannophilus favored ethanol production over that of xylitol while C. guilliermondii favored xylitol formation. However, as the extent of biotin limitation increased, the ratio of ethanol to xylitol produced by both organisms increased. The results are of interest in efforts to control such ratios.
